| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Corrosive to skin, eyes and respiratory tract. Very toxic by inhalation. May cause sensitization by skin contact. May cause cancer. |
| Primary Routes of Exposure: | Contact with skin and eyes. Inhalation of dust. |
| Eye Contact: | Corrosive to eyes. Thermal burns and ulceration of the eyes may occur on direct contact. |
| Skin Contact: | Corrosive to skin. Thermal burns and ulceration of the skin may occur on direct contact. May cause sensitization by skin contact. |
| Inhalation: | Very toxic by inhalation. Inhalation of the dust will cause burns to the nose, mucous membranes and respiratory tract. |
| Ingestion: | Ingestion will cause burns and perforations of the gastrointestinal tract. |
| Acute Health Effects: | With moisture or human contact, metal rapidly forms caustic and highly corrosive alkali hydroxide with evolution of heat. Severe thermal and chemical burns will result. |
| Chronic Health Effects: | No information on long-term chronic effects. May cause cancer. |
| NTP: | No |
| IARC: | No |
| OSHA: | No |
| SECTION 4: First Aid Measures | |
|---|---|
| Eye Exposure: | Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention. |
| Skin Exposure: | Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists. |
| Inhalation: | Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. |
| Ingestion: | Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel. |
| SECTION 5: Fire Fighting Measures | |
|---|---|
| Flash Point: | no data |
| Autoignition Temperature: | 120-125?C (alloy) |
| Explosion Limits: | none |
| Extinguishing Medium: | carbon dioxide, dry powder or foam. Do not use water |
| Special Fire Fighting Procedures: | If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing. |
| Hazardous Combustion and Decomposion Products: | If involved in a fire, burning metal may produce corrosive fumes of potassium and sodium oxide and hydroxide. |
| Unusual Fire or Explosion Hazards: | Highly flammable material. Contact with water liberates extremely flammable or explosive gases. |
| SECTION 6: Accidental Release Measures | |
|---|---|
| Spill and Leak Procedures: | In case of a spill, the material should be covered with dry soda ash, limestone or sand. Place in open container. Flammable hydrogen evolution may occur if wet. |
| SECTION 7: Handling and Storage | |
|---|---|
| Handling and Storage: | Store in a tightly sealed container. Keep in a cool, dry well-ventilated place. |
| SECTION 8: Exposure Controls and Personal Protection | |
|---|---|
| Eye Protection: | Always wear approved safety glasses when handling a chemical substance in the laboratory. |
| Skin Protection: | Wear protective clothing and gloves. |
| Ventilation: | Handle the material in an efficient fume hood. |
| Respirator: | If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134. |
| Additional Protection: | Prepare for the possibility of fire. |
